The Born-level contributions to \(Zj\)  production are given by the two channels
\(pp \rightarrow \mu ^+\mu ^- + q/g\), where \(q\)  represents a massless quark or
anti-quark.
Jet angularities become non-trivial upon inclusion of additional radiation, which in
general purpose MC generators is accounted for by parton shower simulations [1]}.
However, to properly include non-logarithmic corrections,
e.g. from hard real emissions, these should be matched to
exact higher-order matrix elements, as obtained, for example using
event generators such as
MCFM  [2]}, [3]}, [4]},
POWHEG  [5]}, [6]}, [7]} or
MADGRAPH5_aMC@NLO  [8]}, [9]}.
Here we consider simulations including the complete set of NLO QCD corrections to the
\(Zj\)  and \(Zjj\)  production processes matched to the SHERPA parton shower in
the MEPS@NLO formalism [10]}. To address the sensitivity of the
angularities to non-perturbative corrections we also account for UE contributions to
the collision final states and model the parton-to-hadron
transition. In this section we describe the calculational setups for our
Monte Carlo simulations and then present corresponding predictions for the
groomed and ungroomed LHA, Width, and Thrust angularities.
